Design of an ISO 23247 Compliant Digital Twin for an Automotive Assembly Line

The integration of Industry 4.0 (I4.0) technologies is transforming various society sectors, and particularly the manufacturing sector, promoting a digital transformation that fosters smart and interconnected systems. The Digital Twin (DT) acts as a key component in the digital transformation landscape and its integration with I4.0 technologies paves the way for the implementation of Zero Defect Manufacturing strategies. A spotlight on the automotive industry underscores the power of DT applications for real-time defect detection and improvement of product quality and process efficiency. However, the proper DT implementation, contributing to their integration and interoperability, requires the compliance with standards and reference architectures. Having this in mind, this paper describes the design of a DT architecture compliant with the ISO 23247 standard and aligned with the RAMI 4.0 to cover the dimensional measurement process comprising inspection stations placed in the body shop area of an automotive assembly line. This implementation enables the real-time and early identification of defects along the assembly process, allowing to prevent their occurrence at a single stage and their propagation to downstream processes.
